SOLDERlNG-BLOCK.

SPECIFICATION forming part of Letters Patent No. 567,674, datedSeptember 15, 1896. Application filed April 7, 1896. Serial No. 586,599.(No model.)

To all whom it may concern:

Be it known that I, VERNON HENRY BAL- LARD, a citizen of the UnitedStates, residing at Chippewa Falls, in the county of Chippewa and Stateof Wisconsin, have invented a new and useful Soldering-Block, of whichthe following is a specification.

This invention relates to improvements in soldering-blocks of that classadapted for use by jewelers; and it has for its object to provideimproved means whereby rings having sets of diiferent characters,especially pearls, may be soldered without the necessity of the removalof such sets or liability of the same burning, and also by the use ofwhich tarnishing of the head of the ring will be pre vented, and wherebythe ring may be easily soldered with great rapidity.

To this end the invention consists sub stantially in the construction,combination, and arrangement of parts, as will be hereinafter fullydescribed, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a perspective View of asoldering-block constructed in accordance with the present invention.Fig. 2 is a transverse sectional view thereof. Fig, 3 is. a top planview of the block with the cover removed. Fig. 4 is a bottom plan viewof the cover of the block. Fig. 5 is a detail perspective view of one ofthe clamping-plates.

Similar numerals of reference indicate corresponding parts throughoutthe different figures.

Referring to the drawings, 1 designates a block formed of any suitablematerial and having a bottom section 2 and a cover 3 therefor. Supportedwithin the bottom 2 by means of a standard 1 is a cup 5, adapted toreceive and hold any suitable cooling medium, for a purpose to behereinafter described. The cover 3 is provided with an annular flange 6,which passes into the bottom section 2. As clearly shown, said cover 3is also provided substantially at its center with a slot '7, throughwhich the ring to be soldered is passed, and at each end of the slot 7is 10- cated a clamping-plate 8. Each of these clamping-plates is formedof a single piece, and the upper end 9 thereof is bent so as to slidealong the sides of the slot 7. The lower end 10 of said clamping-plateis bent up wardly and liesin a plane substantially parallel tothe upperend 9, but on the under side of the cover 3, and the portion of theplate intermediate the upper and lower ends thereof is bent atapproximately right angles to such ends, thereby forming adownwardlyextending lip 11, adapted to contact with the ring beingsoldered. It will be seen that the lip 11 is provided at its sides withnotches 12, such notches receiving the edges of the slot 7, which form aguide for the clamping plates 8. Pivoted to the under side of the cover3, and at each end of the slot 7, is a segmental shifting-bar 13. Thediagonally opposite ends of the shiftin g-bars are provided with screws14:, which project upwardly through segmental slots 15, formed in thecover 3, and mounted upon these screws 14: are thumb-nuts 16, adapted tobe screwed down upon the cover 3 and bind the shiftingbars 13 at anydesired point in the slots 15. As clearly illustrated, the upper andlower ends of the clamping-plates 8 embrace the shiftingbara and aresecured thereon by means of a screw or its equivalent 17, provided witha nut 18. Thus it will be seen that when the shifting-bars 13 are movedthe clamping-plates are carried thereby and the lips 11 are forcedagainst the ring in the slot 7 Mounted upon the outside of the cover isa sliding plate 19, composed of a substantially rectangular section20-and a triangular section 21. These sections are loosely connectedtogether by means of a screw 22, provided with a nut 23. guide-slot 24,which is approximately at right angles to the slot 7, and by means ofsuch guide-slot the sliding plate 19 may be placed into a position andthe sections thereof spread apart, so as to cover the slot 7. It will benoted that the edges of the sliding plate 19 immediately adjacent to theclamping-plates 8 are cut away, as at 25, such cut-away edges beingdesigned to receive the ring and hold the same.

From the "foregoing the operation and advantages of the herein-describedsolderingblock will be readily understood by those skilled in the art.When it is desired to sol- This screw passes through a der a ring,thesame is placed within the slot 7. The shifting-bars 13 are then movedtoward each other until the scam in the ring is closed, the slidingplate 19 moved to a position so as to completely cover the said slot,and by means of the screw 22 such plate is held in said position. henthe thumb-nuts 16 are screwed upon the screws 14, the same bind the bars13 in the position described, thereby holding the ring within the slotwithout the aid of binding-wires or similar devices heretofore used. Thesections of the sliding plate 19 are then forced apart longitudinally ofthe slot 7, the cut-away portions 25 receiving the ring. Charcoal,asbestos, or equivalent material is placed upon the sliding plate 19,and when the cup 5 in the bottom section 2 of the block has been filledwith a cooling medium, preferably water, the cover 3 is placed upon thesection 2, the set of the ring entering the cup 5 and being immersed inthe Water of the said cup. The function of the charcoal, asbestos, orequivalent material is to reflect the heat, since in the solderingoperation it is necessary to employ means for this purpose, so as tocause the flame blown upon the article being soldered to melt thesolder, and to accomplish this end a lump or wedge of the charcoal,asbestos, or equivalent material is passed through the ring under theseam for the purpose stated, said seam being soldered from the outsideof the ring. The seam of the ring may be easily soldered with greatrapidity, and by reason of the set being disposed in the cooling mediumcontained in the cup 5 it will be obvious that all liability of burningsuch set or tarnishing of the ring willbe entirely overcome. By reasonof the construction of the sliding plate 19 the same will prevent thecharcoal or asbestos passing through the slot 7 or the water in the cup5 boiling through such slot and over the cover 3. While I term the part3 a cover, it is obvious that it need not be a complete cover for thebottom section, as its sole purpose is to receive and support theclamping devices for the ring or other article being operated upon.

Changes inthe form, proportion, and the minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of this invention.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is-

1. A soldering-block, comprising a bottom section, a cover therefor, andmeans carried by the cover for holding the article to be soldered ontheblock, substantially as set forth.
